I like this approach, I am trying to exclude the inserting of a break if the string in the sentence its a link starting with "http", it gets complicated I guess: 
my $str2 = "Be careful what you wish for you just might get it http://
+www.perlmonks.com/?parent=943112;node_id=3333 ---------------test----
+-------resutls----------!";
(my $break3 = $str2)=~ s/([^http.*?\s+]\S{30})/$1 /g;
print "\n\n$break3\n\n";
